Lipopolysaccharides 脂多糖; LPS

产品介绍

Lipopolysaccharides (LPS) 脂多糖是从革兰氏阴性菌外膜的外叶中提取的内毒素，由一个抗原 O- 特异性链、一个核心寡糖和脂质 A 构成。Lipopolysaccharides 是一种激活免疫系统的致病相关分子模式 (PAMP)。Lipopolysaccharides 激活免疫细胞的 TLR-4。本产品来源于大肠杆菌 O55:B5。Lipopolysaccharides 诱导细胞迁移体的分泌。

生物活性

Lipopolysaccharides (LPS) is an endotoxin derived from the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharides consists of an antigen O-specific chain, a core oligosaccharide and lipid A. Lipopolysaccharides is a pathogenic associated molecular pattern (PAMP) that activates the immune system. Lipopolysaccharides activates TLR-4 on immune cells. This product is derived from Escherichia coli O55:B5. Lipopolysaccharides induces secretion of cell migrasome^[4].

体外研究

Lipopolysaccharides (10–80 μg/mL) selectively decreases THir (tyrosine hydroxylase immunoreactive) cells and increases culture media levels of interleukin1β (IL-1β) and tumor necrosis factor-α (TNF-α) as well as nitrite (an index of nitric oxide (NO) production)^[5].

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

Lipopolysaccharides (1.5 mg/kg; i.p.; once) induces sickness and hypothermia in mice, and induces a greater and more prolonged sickness response in adult male mice.

Animal Model:	Female and male CD1 mice
Dosage:	1.5mg/kg
Administration:	Intraperitoneal injection, once
Result:	Induced sickness behavior in all mice, but adult mice displayed more sickness than pubertal mice and adult males remained sick for a longer period of time than adult females. Caused a decrease in body temperature for all mice, but this decrease was greatest in adult males. Increased pro- and anti-inflammatory cytokines at various levels in pubertal and adult male and female mice, resulted in age and sex differences in cytokine concentrations following immune challenge. Only adult males and females treated with LPS displayed significantly more IL-6 than their saline controls, and pubertal males and females and adult females displayed significantly more IL-10 than their saline controls. All the mice displayed significantly more IL-12 and TNF-α than their saline controls.
